Unfortunately, I also suffered LCD screen failure of Surface Pro4 like the most of people. I don’t know how to called this issue but I believe you know.
Now I’ve purchased a brand new LCD pannel from Chinese Taobao to replace its original pannel Samsung LTY123YL01-005 (AIDA64 shows -001 though). I’ve learned from forums and websites that Samsung’s screen for Pro4 has flaws and Microsoft switch it to Pro5’s LG LP123WQ1 at the last batch. So I also purchased LG’s.
The seller told me that connector cable also needs to be replaced because Samsung’s is not compatible. After a few days I received my new scrren and connector. But after installation I can see nothing showing on the new screen, it was totally black including the backlight.
I’m confused. Is that old Surface Pro4 model incompatible with new LG screen? The new connector can connect scrren to mainboard correctly and OS boots normally but I can’t get any image. Another thing is I discovered this new connector’s solder joint having some problems. AIDA64 cannot find new pannel’s name(viewed from Microsoft RD) and I doubt that the seller sending me a bad connector.
Now I’ve bought a new connector from another seller and it’s on the way. But I still holding the question. Can Surface Pro4’s Samsung screen being replaced by LG’s directly? Did anybody also completed the same replacement?
Ordered one more cable from another supplier and the screen works great! Finally, it was cable’s problem. NOTE: AIDA64 was unable to detect LG screen’s data and shows “Surface Display [NoDB]“ under displayer page. Unsure it was the screen or driver’s issue.
Where can you get the lg screen from and the cable?
